Roundabouts are increasingly popular due to their enhanced traffic flow and safety characteristics. TRB hosted a webinar on Thursday, December 16, 2021 that addressed the pavement aspects of roundabout design and construction. Presenters discussed designing roundabouts with innovative concrete pavements, including continuously reinforced concrete pavement (CRCP) and precast concrete pavement (PCP).

This webinar is sponsored by the TRB Standing Technical Committees on Roundabouts and Other Intersection Design and Control Strategies, Design and Rehabilitation of Concrete Pavements, and Project Delivery Methods.

The slides and recording are available.
